Official Government announcement for Israeli tourists 2021
Since March 24, 2021 permanent residents of Israel may visit Greece without having to stay in quarantine anymore. Conditions are that they must have completed vaccination at least 14 days prior to trip and have a negative PCR test within the last 72 hours before entering Greece. Now, don’t hurry to travel to Greece now because restriction measures applied to Greek residents are applicable for visitors as well. Meaning you will not be able to travel around you visit Greece now. However, from end of April – beginning of May, this restriction will probably loosen, and traveling will be allowed as well as other activities. So, if you are permanent resident of Israel and don’t have plans for this summer, start planning a trip to Greece!!!
